Resumen:
A number of strategies to perform parallel query processingin large scale Web search engines have been proposed in recent years.Their design assume that computers never fail. However, in actual datacenters supporting Web search engines, individual cluster processors canenter or leave service dynamically due to transient and/or permanentfaults. This paper studies the suitability of efficient query processingstrategies under a standard setting where processor replication is usedto improve query throughput and support fault-tolerance.
